The Process of Decision Making in Chess Volume 2: Practice positions and solutions. Position 11.2

Solve the challenge below:

Diagram 11.2- white has two “real” weak squares (that the opponent can successfully use to his favor), c4 and f3. Another weakness is the g4 square, also associated with a threat, however that threat is manageable.

Challenge: what is the best way to deal with the threats related to white’s weak squares? Are there weaknesses that do not need attention in advance, before the opponent uses them?

The first move I'm thinking about is Bishop takes Knight... doesn't that Knight potentially cover some of those squares?

qc3 can help or not
